Definitions

  • the invention relates to a punching tool and a manufacturing method for this.
  • punching tools For the production of components consisting of sheet metal, such as plugs or the like, as well as for the production of other parts made of metal or other materials, are often punching tools whose basic basic structure is always similar.
  • a punching tool consisting of a lower tool and an upper tool.
  • the lower tool includes a cutting plate with a flat surface and punched openings formed therein.
  • To the top tool includes a stripper plate with guide holes through which the shanks of punches protrude. The punches are held with their upper ends in a head plate.
  • a punching tool same principle is for example also from the DE 28 14 967 refer to.
  • This punch also includes upstanding from the lower tool guide columns for guiding the upper tool and spring means which clamp the guide plate with closing tool resiliently against the lower tool and thus can clamp a sheet metal part.
  • punching tools can be used to perform a punching work step on a workpiece or to carry out a machining sequence.
  • the latter tools are referred to as punching sequence tools or as progressive dies.
  • Such is from the DE 10 2006 041 494 B3 to remove.
  • the illustrated there tool is used to produce sliding bearing elements, which are punched out of a band.
  • the stall quantity, the quality of the workpieces produced and the working speed, i. the achievable number of strokes, depend considerably on the precision achieved in the tooling.
  • the production and finishing of the punches, in particular the punches and the cutting plate and ensuring a precise guidance of these parts in relation to each other but represents a significant cost factor. This is especially true when, as required for high levels, high-strength materials for the punches and / or the cutting plate can be used.
  • the tool according to the invention can serve the metal or plastic processing. It can be designed for processing sheet metal or plastic films. As active tool components, it includes punches and dies that meet the highest quality requirements by using electrochemical metal removal technologies. This concept allows a high saving of manufacturing effort in the tool production.
  • the tool includes at least one lower tool with at least one punch opening and at least one punch with a working portion which is adapted to dive into the punch opening, and with the Punch opening defines a cutting gap.
  • the punch has apart from a possibly existing head along its length at least two different cross-sectional contours. Preferably, the two cross-sectional contours differ both in terms of their shape and in terms of their size.
  • the punch can be provided with a head, which serves for its attachment.
  • the punch has a shank with a first cross-sectional contour and a working portion with a second cross-sectional contour, which differs from the cross-sectional contour of the shank.
  • the cross-sectional contour of the working section has been produced by an electrochemical removal method. This can be carried out with a flat sheet metal electrode which has an opening corresponding to the cross section of the working section.
  • the electrochemical removal process is limited in the working process to an axially progressing annular zone of the working section which remains constant in its axial extent.
  • the cross-sectional contour of the stem is in another manufacturing process, e.g. produced in a grinding process.
  • the working portion and the shaft portion of the punch are made of the same material. They are seamlessly interconnected and form a one-piece component.
  • the punch can be processed in its final hard condition. Especially in the area of the cutting edges, no thermal load on the material and no material softening occurs.
  • the stamp can be worked out of a blank with great hardness. Is a thermal hardening process, for example required, this can be performed on the blank. Any dimensional changes that could occur during thermal curing, for example by distortion, thus play no role for the accuracy of the punching tool.
  • the electrochemical removal process has no appreciable heat input into the punch. Hardness changes of the punch surface are therefore not to be feared by the electrochemical removal.
  • the shape, in particular the cross-sectional contour, of the working portion can be made almost arbitrary within wide limits. Contours can be produced which can not be produced by the wire-eroding method or by the grinding method. In particular, it is possible to produce a straight, stepped transition between the shank portion and the working portion.
  • the shaping of the working section by electrochemical removal offers the advantage that both the cross-sectional contour and the end face of the punch can be machined, if necessary. Further, for example, filigree, ie thin-walled cross-sectional contours can be achieved on the working part of the punch, which, if they would extend over a greater length, for example the entire shaft, would not have sufficient axial rigidity. Also, if necessary, the punches do not have a guide in the stripper plate - specially shaped guide bushes adapted to the stamp (s) are superfluous.
  • the invention provides Concept a variety of new design options for punching tools and progressive tool, which increase the manufacturing precision and reduce manufacturing costs.
  • the proposed concept can also be applied to punching tools whose punching dies are guided in a guide bushing.
  • the punch can be precisely guided so that its working section meets exactly in the punch opening.
  • a reference surface can be formed on the punch, preferably on its upper, away from the working portion end face. This reference surface may be assigned to the top plate a contact surface against which the punch is clamped.
  • a guide plate for guiding the punch on its shaft is then superfluous as mentioned. This concept can be used to create punching tools or punching tools with higher accuracy.
  • the reference surface of the punch may be a plane surface.
  • a form extension may be formed, which fits into a corresponding recess of the top plate.
  • This mold surface is preferably produced by electrochemical removal.
  • the associated recess in the top plate can also be produced by electrochemical removal.
  • the shapes formed at the upper end of the punch and in the top plate are preferably complementary to one another.
  • the mold formed on the punch may have a slight taper toward its end to effect an interference fit upon insertion into the head plate. In this way, punches can be releasably or permanently connected to the top plate.
  • the backup of the stamp or on the top plate can be effected by fastening screws or cohesive connections, such as braze joints.
  • the punches of the punch or the step tool are processed at their working parts simultaneously by electrochemical removal. This is preferably done when the punches are already mounted on the top plate.
  • high precision can be achieved not only with regard to the shaping of the individual cross-sectional contours of the punches, but also with regard to their alignment with one another.
  • the cross-sectional contours of the punches is preferably a thin consisting of a sheet of electrode with openings that determine the cross-sectional contours of the working sections of the punches.
  • the electrode for producing the punched openings in the cutting plate has correspondingly shaped projections serving as countersunk punches.
  • the contours of the openings in the electrode sheet and the contours of the Countersink dies for producing the cutting plate do not coincide with each other identically. Rather, they have constant or varying degrees of addition along their respective circumference.
  • FIG. 1 As an example of a tool according to the invention, a punching tool 1 is illustrated, to which an upper tool part 2 and a lower tool part 3 belong.
